T all whom t may concern.-

Be it known that I, THOMAS HAWKINS, a

citizen of the United States, residing at 40.

Marchmont street, Russell Square, London, England, have invented certain new and useful Improvements in and Relating to Cham-4 f is both sanitary and sightly and which enfables the vessel to remain perfectly silent in use, meeting a great want, especially in dormitories, hospital-wards, thinly-partitioned houses, and rooms occupied by several persons. My invention or appliance has the fur-` ther merits of being easily cleanable, the upper part being separable from the lower, very light to handle, easy to mold or manufacture, applicable or adaptable to vessels of different sizes, and readily and quickly fixed in position. The lower part may remain as a permanent fixture, if desired, the upper portion, which is above the level of the contents of the vessel, being capable of being lifted away without causing any dripping of Water.

According to my invention I combine a shallow funnel with a short stem or post in such a way that the latter may stand upon or be fixed to the bottom of the vessel, being seldom or never removed therefrom, while the funnel is removable, but rests normally upon said stem, its outer circumference litting easily within the rim of the vessel a little below the top edge. The funnel preferably carries a ange and also rings or equivalent means for facilitating removal. The stem or post is adapted to conduct liquid upon its outer surface from the funnel into the chamber-pot and is constructed and applied as hereinafter set forth.

Referring to the accompanying drawings, Figure lis a section of a pot, showing my appliance contained therein, part of the funnel being in section; Figs. 2 and 3, plan and crosssection, respectively, of a rubber suction disk and stem, forming part of my appliance; Fig.

1l, a section of the stem or post shown upon an enlarged scale, and Fig. 5 an elevation of the stem or post with a modified form of at tachmentto the bottom of the pot.

The shape of the stem or post may be very slight-ly conical, narrowing from the base upward. The topmost portion A (shown more fully in Figs. 4 and 5) may be made of opaque glass or other suitable substance and hollowed away at certain intervals, leaving radial wings C and intervening gaps for conveying the liquid away down the sides of the post into the vessel, as shown by the arrow, Fig. l. Said gaps are curved at top and bottom and merge into a rounded shoulder D, so as to prevent any lodgment of matter. Said funnel is preferably made to rest upon ledges E 'at the base of the wings C, as it is not always convenient for it to be made so accurately (especially if made of clay) as to bite evenly upon the wings and be supported thereby rigidly in a level position. The top of the post is rounded or cone-shaped and is of such a height as to rise up within the funnel B, leaving a free passage through the gaps, or I may provide a small dome independent of the post and attached to the funnel above its central opening.

The post is constructed in one of two ways, according toits intended mode of attachment to the pot. I prefer to employ the suction principle, as illustrated in Fig. 4, this being the form adapted to a chamber-pot already manufactured without anypreparation being necessary. For this purpose I take a disk H, of soft rubber, (shown in Figs. 2 and 3,) similar tothe kind used for attaching candleholders to windows, and I pass through the center of same a second stem J, mounted on a small plate J. The lower part K of the post is preferably molded from clay or porcelain or other like substance and is glazed upon its surface. The upper part A is divided from the lower part K by a water-tight joint L,pro vided with suitable packing, (cloth, by preference,) and the complete post is entirely non-porous and smooth upon its surface. The interior of the post is hollow, and the upper part carries a central block or core IOO small metal plate Q, attached 4to the core by.. screws R R. A rabbet is formed inthe bottom edge of the post, as atS, adapted to fit over the rim or edge of the suction-disk H, aforesaid, but being rather shallower than the same.

disk lies within the said rabbet S, and the rubber will then slightly 4project below 'the' The post, together withA bottom of the post. its suction-disk, is now ready for application to fthe'inside base of .the pot, where it'can be causedtoV stand `upright and iirmly adhere to the surface of sameby simply applying -it irmly and gently to the surface andithen commencing to turnthe upper part A-around several times, .thus drawing up the screwed' stem J within the core M. The hole VOin vthe latter may be stopped at asuitable ypoi-nt to limit the` travel of the spindle to thepoint atV which thesuctiondisk Hwill have been pulled up against the opposing force of thevacuum' with the greatest efficiency and prospect of the vacuum being maintained for a'considerable length of time. `I have found by eXp-peri-k ment that -the vacuum remains unaffected `evenafter several months,'provided that ai4 the center of Vdisk H becomes drawn up inthe form shown in Fig. 4.

Instead of the above-described method of? attachment yof the postI may dispense alto-, gether with the suction principle and employi` a bolt'T, (shown in Fig. 5,) passingt'hrough the post (which'may bein one piece) and also through the bottom ofthe chamber-pot, upon the lower side'of rwhich a threaded locking-f nut U may be screwed. The bottom edge of -f The screwed stem J should be screwed into the .nut `l? .until the edge yof the .n

the .post is in .this case furnished with a W`ater-.tight packing V, let into'a-.groove The interior of the post being always kept isolated from the surrounding liquid is not subject to injury or decay. The rubber disk remains ina good state of preservation, and

Vthe vacuum (where such is used) lasts for a great length of time, a turn of the post being sufficientto restore it, if necessary.

The funnel B is provided with a short tube or depending rim W, projecting below the cen-ter hole and made slightlytaper, so as to surround the wings C and rest upon the ledges `E aforesaid.

The appliance aforesaid may be manufactured in earthenware, metal, glass, vorpartly in kone material and partly in another. The stem or post may, if convenient in manufac-v ture, be formed(in whole or in part) in one piece withthe chamber-pot orlikevessel dur'- ing the process of manufacture of the latter.

Having thus described my invention, what I claim as new, and desire to secure'byLetters Patent, is-V l. For use in a chamber-pot or like vesselJ the combination of a postadapted to be rigidly fixed Atherein and a removable funnel restingupon said post and separable V.therefrom, -such post having radial wings and intervening gaps, wherebythe liquid may be conducted away from the funnel into the'vesseldown the outer surface of the, post, the whole substantially as described.

` 2. For use ina chamber-poter likevessel, the combination `with a removable funnel of a supporting-post,'a'partially-hollowblock or core Ywithin the upper part of said post, a

.screwed nut iixed'within the mouth of said block or core, a screwed stem workingtherein, said 4stem and nut being revoluble in re- Al-artion'to each other, and a suction-disk carried .upon said screwed stem, the wholesubstantially as described.

- In witness whereof I have hereunto-set my .hand in lthe presence of `two* witnesses.
